Steven Avery, one of the key subjects of Netflix’s Making a Murderer, will discuss the murder case that put him behind bars in an interview with Dr. Phil airing on October 3 and 4. While Avery will be phoning in from prison — he’s currently serving a life sentence in Wisconsin for the 2007 murder of Teresa Halbach — his new fiancée Lynn Hartman will appear in the studio. Avery’s nephew Brendan Dassey was also convicted of the murder in a separate trial; his conviction was overturned in August, though the state is appealing. Netflix recently renewed Making a Murderer for another season, which will follow up on both cases.
